SUBM-ARINE DESTROYER.

T 0 all whom it may concern Be it known that I, CARI. J. LINDQUIST, acitizen of the United States of America, residing at New York city, inthe county and State of New York, have invented new and useful SubmarineDestroyers, of which the following is a specification.

This invention relates to vessels. I I

This invention has utility when incorporated in readily mobile bodies,especially for naval service and submarine reconnoitering.

Referring to the drawings:

Figure l is a side elevation of an embodiment of the device in a vesselfor naval service;

Fig. 2 is a fragmentaryelevation of the vessel looking into the torpedodischarge tubes or ways; a

Fig. 3 is a fragmentary sectional view of an upper or after portionofthe vessel;

Fig. 4 is a transverse section of the vessel;

Fig. 5 is a fragmentary V16W looking down upon the prow of the vessel; i

Fig. 6 is a side elevation, with parts broken away, of the prow of-thevessel; and

Fig. 7 is a fragmentary detail of the torpedo discharge way and closuretherefor.

The vessel comprises the inner shell or tube 1 which may be of wroughtmetal or boiler plate material and provided with reinforcing orstiffening ribs 2. To protect the vessel from temperature change, andthereby avoid moisture precipitation upon the inner wall thereof, aninsulation'coveringand an armor jacket are provided comprising wrappingsor windings of cable. The inner winding or cable 3 may be of jute orhempen rope or vegetable fiber for the insulation, the outer winding 4being a wire cable for the armor.

The vessel may have a normally inclined position with its prow submergedand forwardly extending. To give the vessel stability for directing andcontrol, brackets 5 may be provided to carry the forward rib or keel 6and the rearward rib or keel 7. The cable wrappings may snugly fitagainst the brackets 5. Enveloping the armor wrappings and the keels 6,7 may be smooth sheathing 8 to minimize water resistance in the vesselstravel.

Adjacent the upper end or stern of the vessel may be disposed a platform9 carrying the bearing 10 from which rises the funnel carrying post 11to the deck 12. Fast with the post 11 is the arm 13 permittingSpecification of Letters Patent. Pgttentted Apr. 26, 1921. Applicationfiled January 28 1916, Serial No. 74,750.

rotation ofthe funnel relatively to the deck 10. From the deck 10 butfast with the funnel 14; is the stairway 16 extending to the hatch17,"which, when the vessel is submerged may be closed to exclude water.In the normal operation when thefunnel is exposed, this may providesupply and exhaust 'air for the occupants of the vessel as' wellas formotor gases, in the event such type of motor is in use. j I The usualsubmergin'g apparatus may be.

used. 7 a p I Adjacent the lower forward end or prow of the vessel maybedisposed the motor 18 having the universal joint 19 extending to vthedownwardly inclined propeller 20. This propeller is engaged by the yoke21 towhich extend the control bars 22 from the steering wheel'23. Theextensions from the keel 6,. ,7, serve as an enveloping housingfor thepropeller. The shifting of the propeller by .the steeringwheel 23 willeifect guiding of the vessel, and, as this is forward of the vessel, thevessel may be turned in a very at once rise to the surface and no dangerof being entrapped in a sunken chamber arises. The e ectiveness of thissubmergence by propeller action may be varied by shifting the waterballast from a tank 24: to a tank 25 by the pumps 26, 27 With theballast in the tank 25, the draft of the vessel or its angle ofinclination will be less. Such adjustment may be desirable in going intoshallow water or for docking.

For observation a Searchlight 28 having the lens port hole 29 may beprovided. Speed indicating and milea e device 30 may he provided, whileinclination indicator 31 may be provided for the operators to determinethedraft position of the vessel. Vari ous decks or shelves 32 may beprovided with communication ways or ladders 33 therebetween.

In the event the vessel is used for naval purposes of attack or defense,torpedo ways 34 may be provided with the discharge openings enlarged. Acrank adjustment support 35 for the forward end of the torpedo 36v mayberocked to give the torpedo the vessels movements, aswell as dischargetorpedoes by approaching the enemy, swinging into reverse and whilefleeing effect the torpedo discharge, ordischarges, as' desired. v. Theconfiguration is such that even when operating with the stern eX- posed,there is relatively a very small object for target, and such targeteifectively armored and of a contour for readily shedoing a missile byhaving the missile glance therefrom instead of having it embedthereinto. v

The sheating 8 may extend over the keel armor 40 on the brackets 5 whilethe hollow interior may be filled with insulation packing' 41' toexclude water therefrom.

The torpedoes 36 may be released from the clips 42 before discharge. Totake care of expansion of water in the chamber 34 as well as remove thewater therefrom for recharging, the pipe 43 is in communication with thechambers 34and extends to the pump 44 that water may be dratwnthereffrom as desired.

What is claimed and it is desired to secure by Letters Patent is: V i iI 1. A vesselhaving a normally floating stern in surface travel, theremainder of the vessel being submerged, a stabilizing rib' extendingfrom the prow touthestern, and

' a propeller at the prow.

2'. A vessel having a normally floating stern in surface travel, theremainder of the vessel being submerged, and means for effectingfloating and submergence of the vessel. I V

3. A submerged prow vessel having its stern upwardly inclined, andshiftable ballast to vary the prow submergence.

4. A vessel having a normally floating stern in surface travel, theremainder of the vessel being submerged, and a ventilating funnelconnected to the stern.

5. A vessel having a normally floating stern in surface travel, theremainder of the vessel being submerged, a ventilating funnel connectedto the stern, and a hatch for closing the funnel.

6. A vessel having a normally floating stern in surface travel, theremainder of the vessel being submerged, a ventilating funnel connectedto the stern, and means for rotating said funnel. J

7. A vessel having its axis normally downwardly inclined forwardly, saidvessel having a way transversely of the vessel extent approximatelyhorizontally disposed to make an acute angle with the vessel axis.

8. A tubular submergible vessel and a condensation elimination housingfor the vessel comprising continuous circularly extending means.

9. A submersible tubular shell vessel, an armor sheathing wrapping forthe shell, and condensation elimination means spacing the armor from theshell. V

10. A submerged prow tubular vessel comprising a housing and a cablewrapping about said housing.

11. A submersible vessel having transversely'of its axis, a torpedodischarge way, the vertical angle between said way and axis beingoblique;

12. A submersible vessel having trans versely of its axis a relativelyfixed explosive directing discharge way axis, one of said axes beinginclined to the vertical.

In witness whereof I 'affix.
